We present a method for 3D surface segmentation based on watershed cuts computed on local curvatures. The segmentation algorithm is applied to artwork database classification by mean of a search engine based on 3D region descriptor bags. The comparison with a search engine based on global descriptors clearly shows an improvement of performances.
